Registration Date 28-01-2023 Organization Institute of Geotechnical Mechanics named after MS Polyakova of the National Academy of Sciences of Ukraine popup.description2 The object of research is the ventilation of dead-end workings of coal mines. The purpose of the work is to develop recommendations for ensuring the dust and gas safety of works during the period of dead-end mining of the C4 layer ventilation shaft when air entering the ventilation jet is released into the ventilation stream, and the outgoing ventilation air jets from the dead-end mining of the 445 side shaft and roll-back shaft of the «Samarska» mine. Research methods - generalization and analysis of results, methods of mathematics. statistics, calculations according to standard methods. As a result of the work, the ventilation of the ventilation cross seam of layer C4 of the "Samarska" mine of the PSD "MINE MANAGEMENT «Dniprovske" PJSC "DFEK Pavlohradvugillya" was analyzed. "Recommendations on ensuring dust and gas safety of works for the period of dead-end mining of the ventilation cross-cut of the C4 layer when releasing the air entering the ventilation jet into the ventilation jet, the exit ventilation jets of air from the dead-end mining of the 445 side shaft and roll-back shaft of the «Samarska» mine have been developed. It has been agreed to issue the exit ventilation jets of air from dead-end productions, subject to the implementation of the developed recommendations for ensuring gas safety. As a result of the application of the developed recommendations, the safety of mining operations is ensured, which is of great socio-economic and ecological importance.  Product Description popup.authors popup.nrat_date 2023-01-28 Close
